A strap fastener assembly which comprises a flat rigid plate-like member and a flexible strap. The plate-like member has an opening extending therethrough in the form of two elongated slots which intersect with each other to form an acute angle. One of the slots is wider than the other. The strap has a thickened portion which prevents it from being pulled through the slot of lesser width but on movement of the strap to the other slot, its thickened portion can be pulled through that other slot.
